Technology advances for engine and driveline systems continue - Mike Woof writes
With the Stage V emissions requirements being introduced in Europe, a number of engine manufacturers have already announced their plans. Leading engine makers such as Cummins, Deutz, John Deere, Perkins and Volvo Penta have all released information regarding the engines that they will be offering.
The new standard introduces the particulate particle count (PN) and applies to all diesel engines above 19kW for off-road applic
Cummins is developing an all-electric powertrain for use in off-highway applications. This move follows the firm’s acquisition of the electric drive specialist Brammo. The system is designed to suit applications such as urban or underground duties, where it is necessary to minimise engine emissions. The package combines battery power with a compact diesel engine, linked directly to a generator. This offers a range-extended vehicle driveline (REEV). The prototype being unveiled utilises a 4litre F3.8 diesel
Scania has become an increasingly popular engine supplier for construction equipment manufacturers, thanks in part to its modular emissions solution approach. Offering a line-up that includes 9-litre and 13-litre straight six engines and a 16-litre V8, Scania has managed to meet Stage IV/Tier 4 Final standards without having to use a Diesel Particulate Filter (DPF).
